启动 X 服务器

我用 KDE 等离子安装了 Arch。我想在没有显示管理器的情况下启动 KDE，并按照 Arch wiki https://wiki.archlinux.org/title/KDE#From_the_console的说明配置文件。但是在我重新启动所有配置后，它显示错误

(II) modset(0): Initializing kms color map for depth 24,8 bpc.
(II) modset(60): Initializing kms color map for depth 24, 8bpc.

/home/user/.xinitrc: line 54: xterm: command not found
xinit: connection to X server lost

然后我回到登录屏幕的 tty1。

我的 .xinitrc 文件

#!/bin/sh

userresources=$HOME/.Xresources 
usermodmap=$HOME/.Xmodmap 
sysresources=/etc/X11/xinit/.Xresources 
sysmodmap=/etc/X11/xinit/.Xmodmap
merge in defaults and keymaps

if [ -f $sysresources ]; then

xrdb -merge $sysresources

fi

if [ -f $sysmodmap ]; then xmodmap $sysmodmap fi

if [ -f "$userresources" ]; then

xrdb -merge "$userresources"

fi

if [ -f "$usermodmap" ]; then xmodmap "$usermodmap" fi
start some nice programs

if [ -d /etc/X11/xinit/xinitrc.d ] ; then 
for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do 
[ -x "$f" ] && . "$f" 
done unset f 
fi

xterm -geometry 80x20+494-0 & 
exec xterm -geometry 80x66+0+0 -name login
export DESKTOP_SESSION=plasma 
exec startplasma-x11 

我的 .serverrc 文件

#!/bin/sh
exec /usr/bin/X -nolisten tcp "$@" vt$XDG_VTNR

我的 .bash_profile

#
# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc
if [ -z "${DISPLAY}" ] && [ "${XDG_VTNR}" -eq 1 ]; then
   exec startx
 fi

所有这些文件都来自 /home/user 。我做错了什么？谢谢！
